CVE-2022-0018Network attack vector

Local credential disclosure via SSO portal authentication

Published Feb 10, 2022 · Updated Sep 16, 2024

Information exposure in Palo Alto Networks GlobalProtect App 5.1 before 5.1.10 and 5.2 before 5.2.9 allows attackers to obtain local credentials. With portal SSO enabled, the client submits the endpoint user's local-account credentials to the configured portal even when the local and VPN credentials differ. Exposure requires a BYOD endpoint or a connection to another organization with mismatched credentials; third-party MITM attackers cannot read them in transit.
